Our study was designed to investigate immunohistochemically the expression of the receptors of the erbB/HER family (erbB1/HER1, erbB2/HER2, erbB3/HER3, erbB4/HER4) in the bovine uterus during the follicular and luteal phases of the sexual cycle, and the relation to ovarian sex steroids. The stage of the estrous cycle in 30 Holstein bovine was assessed based(More)
There is no definite information about the tongue morphology of blind mole rats owing to spreading of these animals to only a certain habitat. For this reason, we aimed to examine the morphological structure of the tongue by scanning electron microscopy (SEM) in this species. In this study, the tongues of four blind mole rats were used and the morphology of(More)
The aim of our study was to determine the distribution of estrogen receptor α (ERα) and progesterone receptor B (PR-B) in the bovine oviduct during the follicular and luteal phases. Bovine oviducts from 23 animals were obtained from a local slaughterhouse. Blood samples from these animals also were taken before death to measure estrogen and progesterone(More)
BACKGROUND Tamoxifen (TAM) inhibits the initiation of carcinogen induced rat mammary tumours and is administrered for extended periods after the initiation of carcinogenesis. It is also a widely used treatment for breast and gynaecological cancer. OBJECTIVE In this study, we aimed to investigate tamoxifen (TAM) administration on vagen development in rats.(More)
BACKGROUND Epidermal growth factor is a low molecular weight polypeptide with 53 amino acids and is known to stimulate cell proliferation and differentiation in a wide range of tissues. The submandibulary gland in the mouse is a rich source of epidermal growth factor and decreased plasma epidermal growth factor levels have been observed after(More)
The localization and distribution of estrogen receptors (ERα) and progesterone receptors (PR-B) in the cervix and vagina of sexually mature bovines during the follicular and luteal phases of the sexual cycle were studied using immunohistochemistry. The estrous cycle stage of 23 Holstein bovines was assessed by gross and histological appearance of ovaries(More)
BACKGROUND AND OBJECTIVE Epidemiologic and clinical studies have indicated that diabetes is a risk factor for periodontal disease progression. The aim of the present study was to evaluate the morphological changes of gingiva in streptozotocin diabetic rats. MATERIAL AND METHODS 30 male Wistar rats that weighed 250-300 g were used in this study. The(More)
The consumption of fruits plays an important role as a health protecting factor. Grapes (Vitis vinifera L.) are believed to have health benefits due to their antioxidant activity. Öküzgözü is the largest among the grape varieties grown in Turkey. Carbon tetrachloride (CCl₄) causes free radical generation in many tissues such as the liver, kidney, heart,(More)
Many pathogens require direct binding to mucosal cells to cause an infection. The mucosal epithelium of the digestive tract, which is covered by a mucin layer, fulfills several protective functions that are essential to maintaining the health of the digestive tract. Mucins are glycoproteins, which are found on membranes and in mucus gels and protect the(More)
INTRODUCTION Growth factors are proteins that bind to specific cell surface receptors that initiate signalling pathways and result in proliferation or differentiation of the affected cells. During gestation, epidermal growth factor receptors (ErbB1-4) and its ligands (epidermal growth factor-EGF, amphiregulin-AREG, neuregulin1-NRG1) play a significant role(More)
